For example, when a car starts from a standstill (zero relative velocity) and travels in a straight line at increasing speeds, it is accelerating in the direction of travel. If the car turns, there is an acceleration toward the new direction. In this example, we can call the forward acceleration of the car a "linear acceleration", which passengers in the car might experience as a force pushing them back into their seats. When changing direction, we might call this "non-linear acceleration", which passengers might experience as a sideways force. If the speed of the car decreases, this is an acceleration in the opposite direction from the direction of the vehicle, sometimes called deceleration. Passengers may experience deceleration as a force lifting them forwards. Mathematically, there is no separate formula for deceleration: both are changes in velocity. Each of these accelerations (linear, non-linear, deceleration) might be felt by passengers until their velocity (speed and direction) matches that of the car.

Academic acceleration

Academic acceleration is the advancement of gifted students in subjects at a rate that places them ahead of where they would be in the regular school curriculum. Because it provides students with level-appropriate material, academic acceleration has been described as a "fundamental need" for gifted students. Although the bulk of educational research on academic acceleration has been within the United States, the practice occurs worldwide.

Impact

Well-administered academic acceleration programs have been generally found to be highly beneficial to students. Effective administration involves ensuring student readiness, both academic and emotional, and providing necessary support and resources. Cohort acceleration programs, in which a number of students are accelerated together at the same time, are often especially effective. However, acceleration programs often face difficulty due to many teachers, administrators and parents being skeptical of the benefits of acceleration. Adults who have experienced acceleration themselves, however, tend to be very well-disposed to the practice.

Acceleration (differential geometry)

In mathematics and physics, acceleration is the rate of change of velocity of a curve with respect to a given linear connection. This operation provides us with a measure of the rate and direction of the "bend".
